I got 11.28. By subtracting 9.72 by 21 to get x alone
Answer:
There are infinite solutions because there is always another number between any two numbers,
Step-by-step explanation:
This is because in the given equation >8 and x < 10 we are not told of the unique numbers we are searching for be it a decimal or a larger number searching for a unit of 9. ie) 8.0009 or searching for specific 9's.
(-6.8)^2 = -6.8 x -6.8 = 46.24
2x = 5
<span>twice x is 5 become equation now.</span>
